1. The wall ingrowths of pri-mary intine of early 2-celled pollen enlarge the surface areas of the vegetative cell plasma membrane, and may facilitate the uptake of nutrients from the anther locule.

2. After completed hydration of protoplast, outermost part of intine shed off , too.

3. The intine of the pollen began to form in the middle stage of uninucleate microspore.

4. The outer surface of the intine is decorated with scale-like plate structure.

5. We concluded that distruption of the intine from K-type cytoplasmic male sterile wheat is one of crucial factors causing pollen abortion.

6. Close examination of that pollen by transmission electron microscopy also showed delayed formation of starch granules and the intine layer.

7. Objective:To compare the curative effect of puncture and fistulation and tubation of intine maxillary sinus and puncture of maxillary sinus in treating chronic purulent nasosinusitis.

8. Product of ATPase reaction was mainly found in plastid, ERs, matrix of cytoplasm, and intine of pollen wall.
